common/cnxk: add BPHY communication with atf

Messages can be exchanged between userspace software and firmware
via set of two dedicated registers, namely scratch1 and scratch0.

scratch1 acts as a command register i.e message is sent to firmware,
while scratch0 holds response to previously sent message.
